Can Audi cars be soundproofed and noise-reducing? Is the effect good?

Yes, Audi cars can be soundproofed and noise reduction. Sound insulation and noise reduction treatment can effectively reduce in-car noise and improve driving comfort and driving safety. The following are some common sound insulation and noise reduction treatment methods and effects.

Good. Audi A6 adopts a variety of soundproofing materials, including high-density sound-absorbing cotton, soundproofing membrane, etc., which are arranged in various parts of the body to effectively isolate external noise. The door sealing is also very good, effectively blocking the entry of external noise.

Good. During the driving process of the vehicle, the tire noise and wind noise are relatively small, and the engine noise is basically absent.Audi Q5L adopts multi-layer soundproof glass and active noise reduction technology, which helps to improve the sound insulation of the vehicle. At the same time, the chassis sound insulation of the vehicle is also quite excellent, which can effectively reduce road noise and tire noise.

Audi A4L, as a medium and high-end car series, has excellent sound insulation and noise reduction. The noise at standby speed is 40 decibels, the noise at 60km/h is 58 decibels, the noise at 80km/h is 60.2 decibels, and the noise at 120km/h is 65 decibels. The streamlined body and its flat chassis reduce the noise of fast driving very well.

Audi Q5 has good sound insulation, good noise control, tire noise and engine noise are very small. At 120, it is basically wind noise, but it is not big.

How to deal with car soundproofing

solution If the sound insulation effect of the vehicle itself is relatively good, the owner does not need to do the whole car soundproofing. Installing a sealing strip to the door can also make the sound insulation effect better, or the tire noise is more obvious, then replace the silent tire or It is to install soundproofing materials on the hub lining plate, which can also improve the sound insulation effect of the vehicle.

The method of car soundproofing. Among the car noise, the most obvious should be the engine noise, but it is difficult to avoid. The simplest and most effective way is to install soundproofing cotton, which can isolate most of the noise. In addition, it is usually necessary to fix the foot glue, etc., which can greatly reduce the noise. Tire noise.

The simplest and most effective way is to install soundproof cotton, which can isolate most of the noise.In addition, it is usually necessary to fix the machine foot glue, which can greatly reduce the noise. Tire noise. The tires are relatively hard, and they will age after a long time, and they are more likely to make noise.

The most important thing is that the quality of car audio has also become thicker; the overall sound insulation effect of the vehicle is poor: install soundproof cotton to increase the sound insulation effect. The scope includes: hood, four doors, trunk lid, trunk. A layer of chassis armor can also be sprayed to achieve the effect of chassis soundproofing.

The methods of arranging the soundproof sealing strip for the whole car are: fixing the sealing strip around the door, fixing the sealing strip on the skeleton around the doorway, and installing the sealing strip on both sides of the door, around the door and around the doorway, so as to double-install the car. The sealing strip installed in the whole car improves the sealing of the whole car.

Applying a layer of soundproofing materials at the position of the car engine chassis, such as waterproof paint, waterproof mud, etc., can effectively isolate vibration and noise. This method is relatively simple, but the effect is not as good as that of soundproof mats and soundproof felts.

Pros and cons of 4-door soundproofing for cars

1. The specific advantages and disadvantages of 4-door soundproofing for cars are as follows. Four-door soundproofing is a special soundproofing blanket attached to the door trim panel to reduce the resonance caused by the thinness of the door sheet metal parts when driving, reduce the loosening of the door trim panel, and reduce the noise caused by metal fatigue and body twisting.

2. If you choose a non-professional modification shop, the sound insulation of the four doors is likely to be inconspicuous, and it will also bring sequelae to the car, and even change the sound effect of your car audio. CarSound insulation refers to a means of strengthening the sheet metal structure of the car through environmental protection materials specially for automobiles and increasing noise-absorbing materials to ensure the reduction of noise in the car.

3. Therefore, installing soundproofing materials can also make the car body more solid, and once a car accident occurs, it can also avoid greater dangers, thus effectively improving the safety index. 05 Disadvantages Although the installation of four-door soundproofing can protect from external interference, when other vehicles honk the horn, the owner can't hear it.

4. The car is a little old and noisy. After the sound insulation of the four doors, the sound insulation performance and comfort are significantly improved. The car is relatively new, and the noise is not serious. After the four doors are soundproofed, there is no obvious difference. Engine noise, tire noise, chassis noise and other noises still exist.
